(Phys.org)—Back in the early thirties, the story goes, a couple of unknown chemists set about betting one another as to whether they could remove the water from a jelly that had been gelled with pectin, without causing ...

(Phys.org)—Glass is strong enough for so much: windshields, buildings and many other things that need to handle high stress without breaking. But scientists who look at the structure of glass strictly by the numbers believe ...

Japanese scientists from the NIMS International Center for Materials Nanoarchitectonics (MANA) have developed a nanostructured sheets film capable of introducing designated genes into animal cells. The scientists also demonstrated ...

Clemson researchers are taking common materials to uncommon places by transforming easily obtainable and affordable materials into fiber. Their findings are published in Nature Photonics, the world's top journal focused on ...

(Phys.org) -- Scientists do not fully understand how nature uses proteins to develop new materials and minerals, but learning more about the natural processes could lead to bioengineering methods such as the biological synthesis ...

A research group headed by MANA Scientist Dr. Qingmin Ji of the National Institute for Materials Science (Japan), in joint study with Prof. Frank Caruso of the University of Melbourne, developed a new elastic capsule using ...

Silicon dioxide

The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with a chemical formula of SiO2 and has been known for its hardness since antiquity. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. It is a principal component of most types of glass and substances such as concrete. Silica is the most abundant mineral in the Earth's crust.
